Another object of thetinvention is toprovide `alruit squeezer or press, embodying as tand and avertically movable plunger'designed` to press the fruit againt 4a :substantially cone-shaped head, provided with knives,1so `that the segmentsofv the .Still another lobject of the invention is to pro-- `vide a` stand wherein the movable `plunger is operated by a treadle, leaving the operators hands free tohandle 4or dispose `of the'juiceand rind of the fruit, during the operation.

With the foregoing and other objects` in view,

`which will appear as Vthe description Iproceeds,

the inventionvresi'des in the-combination and' arrangement of partsy andin the details ofuconstruction hereinafter described and clairned,it being understood `that changes in the `precise embodiment of the invention herein described, may be made withinthesccpeot what is claimed, without departing from the'spirit oi' .theinvention.

Referring to the drawing infdetail, the base' o! ard 8, which is shown as rising therefrom. l

The lower end of .the standard 6 is formed with cutout portions 'I providing guides for the treadle l which is pivotally connected to the base "5,

Operating withinthe tubular standard-r6, and havingpivotal connection with the treadle 8,.is the :plungervrod llLwhich operates through the bearing Il, mounted-within thehollow standard 6, adjacent to the'ftreadle 8. This bearing Il :also

Mounted on the upper end of the plunger rod :|0, is the laterally extended arm I3' to which the cone-shaped plunger I4' is connected. It might be further* stated thatthis cone-shaped plunger is of a diameter 4to vset up a clamping action between the citrus fruit andthe wall thereof, when the .plunger is forced `downwardly over the cones-shaped presser head I5.

The lsupport. 'for the cone-shaped presser head I5, lis indicated by the reference character I6 and is provided with a funnel-shaped bottom Il, the lower reduced extension I8 thereof being held in an opening of the adjustable supporting arm I9.

rBecause of the structure of the Ysupportingarm,

it will be seen that the support I6 may be readily and easily 'removed and replaced, facilltatingthe cleaning ofthe device.

'Ihe .presser head I5 is constructed in such -a way that whole -fruit may be treated to extract thejuice therefrom, and comprisesacone-shaped body portion,constructed of sheet metal material formed 4with circular lines of `.periforations ,a5-V spaced apart, throughoutiQVY-ztlhe entire surface on lirici-Q3"l `view taken y "-40 the stand is indicated4 by the reference character '5, and provides the support for the hollow'stand- .i

thereof. -Blades indicated at v22 are formed on the outer surface of the head I5, and -are,spaced en equal distance apart, the blades, extending from .the

lower end of the head to tlie'lpexthereohwhere 'the blades merge into afsharp phintdeslgned to ,pierce the fruit and hold the fruit in directalignment with the plunger I4 .to insure `a uniform pressure being directed to the fruit iorthe complete extraction ofthe juices thereof.

In the operation of the .devicei the fruit from which the juices areto be extracted, ispositioned on th'pressernead I5, ina manner asv shown in dotted lines in Fig. 1 of the drawing. The operator nowpresses the treadle 8 downwardly, with the result thatthe cone-shaped plungergrips the fruit and forces it downwardly over the presser head I5, the knives operating t0 cut the pulp, while the pressure directed to the fruit, causes the Juices to be forced through the perforations the plunger rod, a supporting arm adjustablyY mounted on the support, a hollow support on said arm, a hollow cone-shaped presser head mounted in the hollow support and having knives exto which one tending longitudinally of 'the outer surface,l

thereof, said knives merging into a point at the l head, said point adapted upper end of the presser to pierce fruit and hold the fruit in position on the presser head,V said cone-shaped plunger adapted to engage the fruit on the presser head and force the fruit over said presser head extracting the juices therefrom, as the treadle is moved downwardly, and means for receiving `the fruit juices from the presser head.

2. A fruit juice extractor comprising a vertical support, a treadle operated plunger rod operating in the support, a plunger at the upper end of the rod and supported laterally of the rod, a coneshaped presser head mountedunder said plunger, said head having circular lines of perforations arranged therein and disposed in spaced relation with respect to each other, blades extending 1ongitudinally of the outer surface of said presser head and merging into a point at the apex of the presser head, said plunger adapted to move fruit downwardly over said presser head, squeezing the juice therefrom, and a container supported under the presser head to receive juice therefrom.
